IBY MEBNEASSIGNIENTB, OHIO, A CORPORATION 0l' SPINNING BOX FOR RAYON SILK.

Applicgtfn led August My invention relates "to spin nng boxes and particularlv'to devices of th1s character utilized for collectin in cakes, rayon silk made from viscose a ter thesame has been set up into a thread in a precipitating bath. The improvements relate 4to means for p reventing the box from fiyingoff the dr1v1ng shaft; means positively causing the cover to stop its rotation when the box 1s stopped; as also, a particular construction .of the box itself in which 'the body of the same 1s formed 'of a suitable composition securely attached' to a metal sub-base. l

'The annexed drawings and the following description set forth in detail certain means embodying my invention, such disclosed means constituting, however, but a .few of the various forms in which the princlple of the invention may be applied.

In said annexed drawings:

Figure 1 represents a vertical, axial section through my improved spinning box,A

showing also a portion of a funnel threadguide, the parts being shown as relativelypositioned, when the box is stopped;

Figure 1 is a fragmentary vertical. section of a slightly modified construction designed eifectively to prevent leakage around the cover of the spinning box;

Figure 2 is a view similar to Figure 1 1n which the parts are shown as relat1vely positioned when the box is rotating at a high speed;

Fivure 2a is a view similar to Figure la in which the parts are shown as relatively l positioned when the box is rotating at a high speed;

FigureI 3 is a partial plan view and partial horizontal section, taken in the planes 4indicated by the line III-.III, Figure 2;

Figure 4 is a plan section, taken in the plane indicated by the line IV-IV, Figure 2' Figure 5 is a plan view of a modified form of box cover and a lock therefor; and

.Figure 6 is 'a fragmentary 4vertical section, taken in the planesindicated by the line VI---VL Figure 5.

Referring to the annexed drawings in which the same parts are indicated bythe same respective ordinals in the several views, the ordinal 1 represents a rayon silk thread, comprised of a suitable number of strands, `fed downwardly from the usual godet wheel 1, 1925. Serial No. 47,456.

to a metal sub-base 13, the particular securey ing means which I utilize being interlocking grooves and tongues formed respectively in the bakelite base 4 and the metal base 13. Preferably,

molded to the metal base 13. The base member 13 is formed with a hub 5 adapted to receive la bushing (not shown) which in the spinnin box 3, when The body of this box. 3 is the bakelite box body 3. isl

turn receives the means for driving the box 3, the same being usually an extension of a motor shaft. A bakelite plug 17 is threaded into the bakelite base 4 above the upper end Vof the bushing and shaft in the hub 5.

The thread 1 Ais fed through the guide 2 into the box 3 when the latter is rotated at the proper speed, resulting in the formation of aylindrical cake 40, asillustrated in Figure 2. It is within the spirit of my inventionto mold the entire box 3 and hub 5 of bakelite, instead of providing a metal sub-base and hub.

In order that the box 3 may not fly off the motor shaft, when rotated at the high speeds to which these boxes are subjected, I

provide a retaining ring 7 adapted to be securely fastened to the motor shaft and being of cup-shaped formation, shown in Figures l and 2, this retaining ring 7 being formed with an upwardly-extending body portion 18 having an upper and outwardly-extending ange 8 formed s. with a peripheral groove 9. Within this groove 9 is positioned an expansible member, such as a rubber friction band12, or a coiled spring or an annular series of alternate blocks and springs, adapted to fly outwardly under the force of centrifugal action, when the box 3 is rotated at a high speed. Depending from the metal base 13 is an annular flange 10 formed at its lower end with an inwardly-projecting shoulder 11, the

as plainly flange 10 lying just outside the flange 8 of the ring 7 and having its-shoulder-11 substantially horizontally aligned with the bottom of the groove 9 formed in the flange 8. It is evident that when the box 3 is rotated at a speed high enough tocause the expansible band 12 to be thrown outwardly under the centrifugal action, the band 12 will frictionally engage the inner face of the flange 10 and the box .3 will be prevented from 'riding upwardly on the motor shaft.

By a lconstruction similar to that described with reference to the preventing of the box 3 flying off the motor shaft, a cover 20 is caused to rotate in unison with the box 3. Referring particularly to Figures 1, 2 and 3, the box 3 is formed with an inner shoulder 25 upon which the cover 2O is mounted, said cover being formed with an outer peripheral groove 23 within which is positioned an expansible member such as a rubber friction band 24. The upper end of the box 3 is formed into an enlarged annular flange 21 formed with an inner annular groove 22 horizontally aligned with the groove 23 of the cover 20. The cover 20 rotates with the box 3 and when the box 3 is stopped, the cover tends to continue its rotation or to be thrown off the box. The expansible rubber ring 24 prevents this result y causing the cover 2O to stop rotating when the box 3 stops, since the ring 24 frictionally engages the wall of the groove 22 in the ange 21 when the cover continues rotating at a speed sufficient to cause the rin 24 to be thrown outwardly by centrifugail action.

Referring particularly to Figures 1a and 2, a slightly modified construct-ion is shown for effectively preventing leakage around the cover. This modication consists in eliminating the shoulder 25 formed at the top of the box 3, upon which the cover 2 rests in the type of device shown in Figures 1 and 2, and orming a peripheral flange 41 upon the cover 20', by means of which the same is sup orted upon the flange 21" of the box 3. urthermore, the upper wall 42 boundin the box groove 22 is beveled so as to provi e positively for the wedging of the expansible ring 24 tightly down upon the lower wall 43 bounding the groove 23 and the lower wall 44 bounding the groove 22. This construction particularly prevents distortion of the silk.

Referring particularly to Fi 6, I/show a modified form o cover and cover lock. The same consists in a cover body 30 formed with an annular series of spaced upwardly-projecting bosses 31 of res 5 and `which Aany two adjacent bosses are adapted to be engaged by the hook-shaped ends 33 of a flexible wire ring 32. The cover 30 rests upon an inner shoulder 35 formed in the upper end of the box 3 and the body of the .ring 32' is positioned in a small inner annular groove 34 formed in an upper flange 36 ofthe box-3. The ring 32 by frictional engagement isvcaused to rotate with the box 3 and the rotation of the ring 32 causes a similar rotation of the cover 30 through its hook-ends 33. Likewise, the stopping of the box 3 stops the ring 32 which in turn sto s the rotation of the cover 30.

hat I claim is:

1. A spinning box formed with a hub to receive driving means, a retaining ring adapted to be actuated by the driving means,

and an expansible member carried by and around'said ring and adapted by centrifugal action to (ngage and hold said box to prevent the latter from climbing upwardly.

2. A spinning box formed with an annular flange, a hub member securedv to the box base to receive driving means, a retaining ring adapted to be actuated by the driving means, and an expansible member carried by and around said ring and adapted by centrifugal action frictionally to engage said annular flange.

A spinning box formed integrally with a hub member to receive driving means, said box being formed with a laterally-extended peripheral upper end flange formed with an inner annular groove, said box being further formed with an inwardly-extending shoulder, a cover resting on said shoulder and having a peripheral flange formed with an annular groove opposed to the box groove, and an expansible member positioned in the groove of said cover and adapted by centrifugal action frictionally to engage the box flange within the groove of the latter.

lll!) llO 7. A spinnin box formed with an annular depending ange, acover for said box, positive means for stopping the rotation of the cover when the box stops rotating, a hub member secured to the box base to receive driving means, a retaining ring adapted to be actuated by the driving means, and an expansible member carried by and around said ring and adapted by centrifugal action frictionally to engage said annular flange.
